The spammers always come from different ip-addresses, use different sender addresses and the content varies too. Suppose you receive spam in which 'professional translations' are offered all the time. When in doubt, you can of course set a list to give penalties and not to stop a mail immediately. In the logs you can always see what a list does. In the image below, you will find three good blacklists. Chances are that people leave their server on the list and you will not receive mail from those parties anymore. Of course, you should not use such lists to check your mail against. You want to take your mail server off the list because the problem has been solved, but then it turns out that you have to pay. Make sure that when you add a blacklist you choose one that mail server administrators can also easily unsubscribe from.Įxample: You get blacklisted because you accidentally spammed. These lists contain addresses from which viruses originate (virbl) or are a collection of other blacklists. That is why there are internet blacklists. However, it is pointless to manually list every ip address that has ever tried to do something.

In white lists, it is useful to include your own ip addresses, for example from the office.īlacklists are useful if you are constantly being attacked from the same range. In Kerio, you can maintain your own whitelists and blacklists, but you can also use blacklists that are available on the Internet (Blacklists). In the header of an e-mail you can see what the score of a message is. If it has more than 6.7 points, it will be rejected. So if a message has more than 3.8 points, it will be marked as SPAM. In the example below, the Tagscore value is 3.8 points. You can indicate when something is marked as spam and when it is rejected. but also where it comes from, how often words are repeated and so on. Think of the title of an e-mail: ATTENTION! THIS IS AN IMPORTANT MESSAGE!. Points are given to properties of messages that are spammy and minus points when properties are not spammy.
